...no rescue because you will send either HEMS or HART to the scene. although RNLI personnel could be CC trained?
fire and police dont really need any training unless missions are created for such use.
coastguard van could be used for missing person/child on a beach, injured person on the pier, or even a whale washed up on a beach. for this POI can be created with Beach, Pier, and lifeguard tower and coastguard van personnel to be CC trained??
Coastguard Rescue Teams are unsurprisingly trained in multi disciplines of rescue. Rope, Water, Mud are the main ones plus missing persons search, royal fish, pollution monitoring and ordinance recognition as well as other stuff. so if you want a 'Coastguard Station' then they need to be represented as a 'proper' rescue organisation. There are normally ten or eleven members per team and i think it's about 3,500 across the United Kingdom supported by four or five Senior Coastal Operations Officers per area.
RNLI, is separate and have boats predominantly plus a few (think it's ten or twelve) flood rescue units around the United Kingdom. RNLI staff have casualty care training to a similar level to CG rescue teams but most definitely not to Critical Care Level (Unless trained and authorised from their 'day' job).
Hope that makes a bit of sense.
